Space Place Value!

The children confidently partitioned teens numbers into tens and units (16=10+6 and so on!) so we have moved on to partitioning bigger 2-digit numbers. The children had to help an astronaut follow a path of asteroids to see which planet he would land on. The only clues they had were how many tens and units the next number had.

We then made our own asteroids and the children had to give their partner instructions using tens and units to direct them around the classroom!

After they had practiced describing the numbers by their tens and units, the children went back to their original activity to plan and record a route to take the spaceman to a different planet.

The children have loved playing Place The Penguins this week. Click on the link below to take you to this game so you can play at home too!

Watch out for the snowballs!

Space Walk Mission!

On Friday the children were issued with a mission from our Space Station control panel. While out on a space walk, the door had locked behind them and they had to work out the code before they could get back into the Space Station.
The children had time to practise using tens and units before they went on their mission!

Once outside, they had to find Space Station doors hidden around the outdoor area and count the tens and units on the back to work out each number.

When they had written down all the numbers, they had to see which number appeared the most. That number was the code to get back inside! It was quite cold out in space so the children were very keen to complete the mission successfully!

The children then made the code number using tens and units to be allowed back in!
Mission completed!
